Application filed j-I My 19,

To all whom l'ijmayroncem:

Be it known {that =1, {CHARLES A. New, 10f lochester, in .the .county of Monroe and State of New York; have invented certain new and useful Improvements in Bottle- Stoppers; and I .do -hereby declare the following to bee full, clear, and exact description of the same, reference bingshad 'to the accompanying drawings, formingga. art ofterfere with (the discharge ofthe liquid the;

this specification, and to :the .re' erencenumerals marked thereon.

The present invention relates ,to bottle stoppers .and it has -5f01 an .object ;to -.;provide animproved constructionemploying a valve opening automatically .to .a position where :it

will not interfere with the dischar ing =ac-- tion when the .bottle is tiltedto discharge. its contents.

Another object is to provide a. construe tion which will permit-the :tree ,fiow .of, liquid from .the bottle and at .the same time prevent all waste due to .dri ping.

To these and other ends t e inventioneonsists in certain improvements and c0mb-ina,-' tions .ofparts, all as will .be: hereinafter more fully described, the novel features be- T ing pointed out in the claims .at the end of j the specification.

In the drawings: Fi ure 1-is an elevation of my invention emb ied as an attachment to bottles; Fig. 2 is a vertical section show.- l ing the stopper in closed position, and 3 1s a vertical-section showing the stopper in discharging position.

In the prment' embodiment the stop er is in the form of an attachment to a hott e but it is apparent that the invention is not limited to this construction. As shown iti comprises a hollow member .consistin of an enlarged or substantially spherical c amber j 3' .with a. tubular portion 4 eat one end surrounded by an"cxternally taperingsleeve 5 1 of cork or other yvielding material adapting it for insertion into the neck ofa bottle 1. At its outer end the hollow member may he ,provided with a flared discharge 6 of frustoconical form which cuts the liquid in such a manner that all dripgtilng is prevented.

Arranged to close i e discharge from the bottle is a valve '7 which preferably seats against the inner wall ofthe-flared dincliarge 6 and is held in this position. by a weight 8 that in this instance operates in vSpeciiieationofmattersiatent.

- port fin this instance being in Patented-Mar. 2, 19 10.

' stem 'Qde ending-from the under surface of the valve.7. -lVhen athezbottl is tilted to d1scharge=..the contents thereof "the .weight 8 :moves. forwardly in :the casing -0r hollow 'member and carries the valve 7 away from theseat t3, the enlarged chamber 3 permit wting the liquid to flow freely above/the weight. 3 To .the end 'thatxthe valve 7 shall not in said valve-is shifted laterally in an upward direction relatively :to its seat, being preferably :at the same time moved outwardly to cleartheseat ti. "'lhis result is accomplished .ref erablyby a support or guide 10 which oose'ly engages the stem 9 between the weight 8-and :the valve .7, the. uide or supille form of a centrally perforated ba-r secured at its ends to diametrically opposite sides of .the cha ns her 3. It .is apparent that this construction 1 therefore move to, a lower point than said valve. I

It is preferred to make the valve 7 in the form iof an inverted time so that'its side walls will'be inclined and slide freely over .the outer edge of the discharge 6.

This stopper has'special advantages when used on bottles from which liquid is frequently dispensed, such for instance as w-h-is'ky bottles and other bottles used in barrooms. \Vhen in an upright position the bottle is effectively closed against-the entrance of dust, flies and bacteria. while the liquid may dispensed alunost instantaneously merely by the tilting of the bottle, the weight '8 moving" forwand and downwards-in the discharge passage causing the valve 7 to -partake of an outward and upward lateral movement. In this position the liquid has a free passage through and from the stopper and is not caused to spread in various directions. Upon the uprighling of the bottle the weight 8 moves in an opposite direction from that which was imparted to it on the opening movement and draws the valve 7 firmly to its seat. the tapered pqrtiou of the the chamber 3 and is rigidly secured to a 'valve facilib ting the closing thereof while permit-s the stem to move forwardly with the sharp outer edge of'the discharge portion 5 cuts the outfiowing stream of liquid and prevents any dripping.

closed the weight 8 shall engage within the tubular portion 4 for otherwise bindlng aeextraneous matter from the interior of the tion will take place between thefseat Sand the guide 10 and the valve will not-open until the bottle has passed the horizontal,

whereas with the present nonstructionin l which a flared portion surrounds the upper end of the tube 4, the valve is moved out-" wardly at the first part of the tilting of the bottle and before the stem engages the guide 10- which afterward effects the upward movement of the valve. Upon the uprighting of 'thebottle the weight enters the upper end of the tubular portion and centers the valve 7. As liquid will remain in the chamber 3 after the closing of the valve 7 it is desirable that the weight should not close the tubular portion t, and therefore it may be provided with ribs 11 on its under side which provide a passageway'for the liquid from the chamber 3 to the bottle. I

From the foregoing it will be seen that not only does this construction exclude the i l l l lnttle but it prevents a great deal of the. I waste that hasheretofore.oceurred. It'is desirable that when the valve 7 1S 1 l'elaiin as my invention: .l. In a. bottle stopper, a tubular portion,

an enlarged chamberhaving a fiared dist-harging portion in proximity to said chainher. a valve seating iii the discharging portion. a stem depending from the valve, a

weight secured to the stem and seating in the end of the tubular portion. and a guide cooperating with the stem between the weight and the. valve.

2. In a bottle stopper, a tubular portion,-.

an enlarged chamber having a flared dis-Q.

charging portion in proximityto said chant her. a vah'e seatingin the discharging por-" tion. a stem depending from 'thevalve, a weight secured to the stem and having ribsseating in the end of the tubular portion,

and a guide cooperating with the stem between the weight and the valve.
